6 Claims.

This invention relatesgenerally to the class of fire extinguishers and refers more particularly to a holder for a frangible container for a' fire extinguishing substance, which holder is so constructed as to permit either the manual removal of the container therefrom and hurling of thesame at a fire for breakage and release of the substance to extinguish the fire, or the automatic gravitational release and dropping of the container in the presence of a predetermined temperature.

The invention aims to provide an improved holder of the character and for the purpose set forth, which embodiesbut -few and simple parts capable of economical productionand assembly, so that the same may be sold at such a low price as to bring the'benefits and safeguards of such equipment within the reach of practically every home, as well as for business and industrial plants, and which holder presents a neat andattractive appearance and is highly efiicient for its intended purpose. V r

With the above enumeratedand other objects in View, reference is now made to the following specification and accompanying drawing in which there has been disclosed a pr'eferredembodiment of the invention, while the claims cover variations and modifications "thereof which properly fall within the scope of the invention.

In the drawing:

Fig. 1 is a perspective view of a holder'constructed in accordance with the invention and illustrating in broken lines the container arranged therein.

Fig. 2 is a vertical sectional view therethrough, respectively illustrating in full' and dotted lines the movable section of the holder in positions for supporting and releasing the fire extinguisher container.

Fig. 3 is a horizontal sectional view taken approximately on the line indicated at 3-3 in Fig. 2.

Referring to the drawing by characters of reference, A designates generally the fixed body-section of the holder, B the movable section, which sections together define a cabinet or holder for a fire extinguisher container designated by the reference character C and illustrated in broken lines.

The body section A includes a vertical rear wall 5 and a pair of forwardly extending vertical side walls 6-6 which are preferably formed integral with the rear wall 5 so that said section A may be inexpensively constructed from sheet material. The relatively movable section B includes a horizontal bottom wall 1 having, at its forward'edge, an upstanding vertical front wall 8 and which walls I and 8 are preferably formed integral so that the'section B may be inexpensively produced from sheet material. The section B is pivotally or swingably carried by the body '5 section A in any suitable manner, so that when it is released, the container 0 will be dropped and broken to release its contents. As shown, the swingable or pivotal connection is established by forming the bottom wall 1 with the laterally 10 projecting, preferably integral, trunnions 9 adjacent its inner or rear edge, which trunnions are journaled in bearing openings [0 formed in the side walls 6 -6 of the fixed body section A. The section B is held against swingable or pivotal movement in a normal position with the bottom wall 1 horizontal and a front walls vertical, by means of bolts 5 l which extend through apertures I2 in the rearwall 5 of the body section and through corresponding apertures l3 in the front wall 8 of the movable section B, the heads M of the bolts lying in'rear of the rear wall 5 and nuts I5 threadedly engaged on the forward terminals of the bolts H and lying in front of the front wall 8 of the movable 'section'B. The shanks of the bolts H are formed intermediate their length with a fusible section it which is fusible at a predetermined temperature, which temperature is slightly in excess of the temperature at which the fire extinguishing substance within the container C generates a pressure. The purpose and object of this is to cause the pressure within the container to effectively scatter the extinguishing substance when the container is automatically dropped by the fusing of the fusible sections Hi.

It will be observed that the bolts i! hold the sections in a normal relative relation to define a box-like structure closed at the bottom, front and rear sides and having an open upper end from which the upper portion of the container C protrudes to facilitate the manual grasping and removal of the container when the same is to be manually thrown at a fire. The holder with the container therein is supported preferably from a vertical surface such as a wall, in any desired manner, but as shown, the rear wall 5 of the section A is formed with a keyhole slot H which is engaged over a nail or other equivalent supporting element I 8. Due to the arrangement of the trunnions adjacent the rear or inner end of the bottom wall I, it will be observed that the preponderance of the weight of the container C supported on V the bottom wall 1 is disposed thereon between the trunnions 9 and front wall 8 so as to cause the section B to swing or gravitate from the normal position shown in full lines to the dotted line position in Fig. 2, when the movable section is released by the fusing of the fusible sections 16 of the bolts I I.

What is claimed is:

1. In a fire extinguishing device, a cabinet for holding a frangible container for an extinguishing substance, including a fixed body section having a vertical rear wall secured to a support and a pair of vertical side walls extending forwardly from the side edges of the rear wall and a movable section including a horizontal bottom wall pivotally connected adjacent its rear edge to the body and having an upstanding front wa1l,'and means releasable under a predetermined heat for holding the movable section with the bottom wall in horizontal position and the front wall in a vertical position to define an enclosure open at the upper end within which the container is arranged and supported by the bottom wall and from the upper end of which the container protrudes.

2. A cabinet for a frangible projectile type container for a fire extinguishing substance comprising a fixed section including a rear wall and side walls and a relatively movable section including a front wall and a bottom wall, a pivotal connection between the rear of the bottom wall and the fixed section, means fusible at a predetermined heat for holding the movable section in juxtaposition to the fixed section to'define a box-like enclosure open at the upper end and within which the container is arranged and supported by the bottom wall with the upper end of the container protruding from. the open upper end of the enclosure for manual grasping and removal.

3. YA holder for a frangible container for a fire extinguishing substance including a fixed section secured to a vertical support and comprising a rear wall and forwardly projecting side walls and a movable section comprising a front wall and a rearwardly directed bottom wall, a pivotal connection between the rear of the bottom wall and the rear of the fixed section and a fusible connection between the front wall of the movable section and the rear wall of the fixed section for holding said sections in relative position so as to define a cabinet open at the top and within which the container is arranged and supported by the bottom wall with the upper end of the container protruding from the upper end of the cabinet.

4. A support for a frangible container for a fire extinguishing substance comprising a fixed section and a movable section hingedly connected therewith and including a bottom wall and a front wall of a, sufficient length and adapted, when the movable section is released, to assume an outwardly and downwardly sloping position, and means connecting the rear of the bottom wall of the movable section with' the fixed section, said means being fusible at a predetermined temperature for releasing the hinged section to eifect the gravitational discharge of the container from the support and the guiding of the same outwardly by the sloping position of the front wall.

5. A support for a frangible container for a fire extinguishing substance including a fixed section having rear and side walls, a movable section having angularly related front and bottom walls, the bottom wall having pivoted connection adjacent its rear edge to the fixed section, and fusible means of connection between the upper ends of the front and rear walls of said sections located adjacent the side walls and holding the sections in juxtaposition to define a box-like cabinet open at the top, within which the container is arranged with the upper end protruding through the open top. 7

6. A support for a frangible container for a fire extinguishing substance including a box-like body open at the top within which the container is arranged'with the upper end protruding from the open top, said body comprisinga fixed section, the latter section including a bottom fulcrumed adjacent its rear edge-to the fixed section and upon which the container rests and an upstanding front wall at the forward end thereof, the fixed section having rear and side walls completing the body and a fusible connection between the front wall of the movable section and the rear wall of the fixed section fusible under a predetermined heat for automatically releasing and discharging the container from the body of the holder.
